Hello there, I updated my software to the latest and now I have problems. Actually, I set up my SMTP, added protocol 587 (tried and 465) and Test email has been sent and delivered normally, but once I try the same from Receipts for example, I’m getting message: An error occurred while attempting to establish an SSL or TLS connection. The server’s SSL certificate could not be validated for the following reasons: • The server certificate has the following errors: • The revocation function was unable to check revocation for the certificate. Any idea what to do? Thank You in advance. ---

> [@Smtp server no longer available](https://forum.manager.io/t/smtp-server-no-longer-available/48587/30): > > Hi Inga, I had the exact same problem like you…test email goes through without issues, but sending invoice or report, error message. In my case it was an issue with email setting in AVG…it seems that scanning outbound emails (SMTP) was creating a problem. Once I deactivated that box, all emails are going through without any issue. If you have something similar in your antivirus program, try to deactivate it and see if that works. Hope this help slight_smile > it was an issue with email setting in AVG…it seems that scanning outbound emails (SMTP) was creating a problem.
